However, after watering, due to long-term exposure to sunlight, it is easy to cause the water to evaporate faster, affecting the efficiency of concrete molding, causing the concrete to crack and peel. In order to maintain the road, a layer of protective film needs to be laid on the road. The use of a film laying device is an existing conventional method, but the existing film laying device has the following problems when used;

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The present invention is provided with an automatic falling and pressing mechanism, which pushes the vehicle body, so that the wheels and the wheel axles rotate, cooperates with the mounting shaft, the mounting rod, the adjusting column, the first transmission bevel gear and the unloading bevel gear to drive the gear roller to rotate, and the gear roller drives the gear ring to rotate, and the pull plate can be driven to move by the push rod and the pull rod, and the pull plate cooperates with the limit spring through the pull rope to make the limit rod reciprocate, and cooperates with the inclined structure at the end of the limit rod, so that the metal stones placed at the bottom of the cylinder can fall in sequence, so that when the vehicle body is continuously moving to perform the film laying operation, the metal stones fall on the protective film in sequence, and the protective film is pressed to prevent the protective film from turning over due to rain and wind, which can improve the protection effect of the highway. In the traditional technology, most of them need to manually place stones or soil piles on the protective film in sequence, which is cumbersome to operate. The present application only needs to push the vehicle body to realize the laying and pressing operation of the protective film. At the same time, the falling of the metal stone is affected by the activity speed of the vehicle body, and can be realized by falling at a fixed distance on the protective film, further improving the uniformity of pressing;

[0021] 2. The present invention is provided with a recovery mechanism for a protective film and a metal stone. The position of the adjustment plate is adjusted by rotating the adjusting screw. At this time, the feeding bevel gear squeezes and contacts the second conduction bevel gear, so that the feeding bevel gear meshes with the second conduction bevel gear. At the same time, the adjustment column can be pushed to move, so that the first conduction bevel gear and the unloading bevel gear are separated. At the same time, the feeding plate can be moved to the bottom of the placement cylinder. Only the adjusting screw needs to be rotated to realize the switching between the falling and the collecting of the metal stone. When the vehicle body is pushed in reverse, the rotation of the wheel and the wheel axle can still be used to drive the rotation of the feeding reciprocating screw rod. Under the restriction of the feeding shaft and the positioning groove, the feeding reciprocating screw rod can drive the movable plate and the feeding plate to move up and down. When the movable plate moves downward, the gear sleeve meshes with the gear plate, driving the feeding plate to flip, so that the electromagnet is located at the lower position. At the same time, the metal head at the end of the feeding shaft and the metal The plates are in contact to achieve conductive connection. At this time, the electromagnet is energized to magnetically adsorb the metal stone at the bottom. When the movable plate moves upward, the feeding plate flips and drives the electromagnet upward. At this time, the metal head is separated from the metal plate, and the electromagnet loses its magnetism. With the continued upward movement of the movable plate and the feeding plate, the metal stone is pushed into the bottom of the placement tube. With the elastic sliding of the limit rod, the metal stone is fixed between the upper and lower limit rods. The continuous movement of the vehicle body can recycle the metal stone into the placement tube in turn when the protective film is rolled up, which is convenient for next use. In traditional technology, the recovery of the compressed objects requires manual picking in turn, and then the recovery of the protective film. The operation process is complicated, time-consuming and labor-intensive. The entire process of the present invention only needs to push the vehicle body to achieve, and the operation is simple. At the same time, the protective film and the metal stone can be recycled, reducing resource waste and saving energy.

[0022] 3. In summary, the present invention can realize the equidistant automatic falling of metal stones when laying the protective film, compress the protective film, and thus improve the protection effect on the concrete road. At the same time, the protective film can be rolled up and recycled. During the recycling process, it is only necessary to rotate the adjusting screw and adjust the position of the movable plate and the loading plate to realize the switching use of the unloading and recycling mechanisms. The metal stones can be recycled by pushing the vehicle body in the reverse direction. After recycling, they can be directly used next time without adjusting the position of the metal stones again. The whole process can be completed by only pulling and pushing the vehicle body. The operation is simple. By recycling the protective film and directly using it next time, resources are saved and manual labor is reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] Working principle: When using the film laying device for highway engineering construction, Figure 1-7, first install the roller 6 wrapped with the protective film on the mounting seat 5, first insert one end of the roller 6 into the mounting seat 5 with the mounting spring 7, and then insert the other end of the roller 6 into another mounting seat 5, under the resistance of the mounting spring 7, install the roller 6, and rotate the adjusting screw 20 to move the feeding shaft 25 to the bottom of the positioning groove 28 in advance. At this time, the feeding shaft 25 can slide horizontally in the positioning groove 28. Under the restriction of the feeding shaft 25 and the positioning groove 28, the adjusting plate 21 is driven to move by the adjusting screw 20, so that the feeding plate 26 is staggered with the bottom of the placement cylinder 8. At this time, the feeding bevel gear 23 is disengaged from the second conduction bevel gear 40. Under the action of the adjusting spring 37, the adjusting column 38 is pushed out, so that the first conduction bevel gear 39 is meshed with the unloading bevel gear 19, and then one end of the protective film on the roller 6 is pulled out and placed on the ground around the bottom shaft rod. The staff pulls the vehicle body 1, the wheel 3 and the axle 4 rotate, and the axle 4 drives the roller 6 through the mounting seat 5 The cylinder 6 rotates to release the protective film, and at the same time, the wheel shaft 4 drives the installation shaft 35 to rotate, and the installation shaft 35 drives the installation rod 34 to rotate through the bevel gear transmission assembly 36, and the installation rod 34 drives the adjusting column 38 to rotate, and drives the tooth roller 18 to rotate through the first transmission bevel gear 39 and the unloading bevel gear 19, and the tooth roller 18 meshes with the gear ring 16 to drive it to rotate, and the push rod 17 on the gear ring 16 contacts with the pull rod 15 in the gap, so that the pull rod 15 is forced to slide outward, and the pull rod 15 drives the pull plate 13 to move outward, and the pull plate 13 drives the limit rod 11 to move through the pull rope 14. At this time, the metal stone 12 loses the limiting force and falls downward, and the metal stone 12 at the bottom falls to the protective film on the ground. At the same time, under the action of the limit spring 10, the limit rod 11 returns to its original position, and through the inclined structure at its end, the metal stone 12 is equidistantly limited again, and the operation is repeated, the automatic laying of the protective film and the automatic falling of the metal stones 12 one by one can be realized, and the protective film is pressed to prevent it from turning over;

[0038] Then, if Figure 1-3 and Figure 6-8When the protective film and the metal stone 12 need to be recovered, the adjusting screw 20 is rotated in the reverse direction, and the feeding shaft 25 slides horizontally in the positioning groove 28, driving the adjusting plate 21 to move, so that the feeding plate 26 moves to the bottom of the empty placement cylinder 8. At this time, the feeding bevel gear 23 is meshed with the second conductive bevel gear 40, and the end of the protective film is fixed on the roller 6 and rotated, and the protective film is initially rolled up, and the car body 1 is lifted to the corresponding metal stone 12 position. At this time, the metal head 31 at the end of the feeding shaft 25 is aligned with the metal plate 2 9 contact, can be internally conductively connected, the battery 2 supplies power to the electromagnet 27, the electromagnet 27 can adsorb the first group of metal stones 12, and then push the vehicle body 1, drive the roller 6 to rotate in the opposite direction, and rewind the protective film. At the same time, the rotation of the mounting rod 34 and the adjusting column 38 drives the feeding reciprocating screw rod 22 to rotate through the feeding bevel gear 23 and the second conductive bevel gear 40, and then drives the movable plate 24 and the feeding shaft 25 to move up and down. At the same time, the gear sleeve 32 moves up and down and meshes with the gear plate 33, which can drive the upper The material shaft 25 and the loading plate 26 are turned over 180 degrees. At this time, the metal head 31 on the loading shaft 25 is separated from the metal plate 29, and the electromagnet 27 is powered off. The loading plate 26 and the electromagnet 27 continue to move upward, pushing the metal stone 12 from the bottom into the placement tube 8. The metal stone 12 contacts the inclined surface of the limit rod 11. The limit rod 11 cooperates with the limit spring 10 to elastically expand and contract, so that the metal stone 12 reaches between the upper and lower limit rods 11, collects the metal stone 12, and continuously pushes the vehicle body 1, so that the loading plate 26 is repeatedly moved upward. The electromagnet 27 is powered on when it is pointing downward to adsorb the metal stone 12, and is powered off when it is pointing upward to lose the adsorption effect on the metal stone 12. The metal stone 12 can be pushed into the placement cylinder 8 for recovery. Since the falling intervals of the metal stones 12 are roughly the same when laying the film, after the first metal stone 12 is collected, the subsequent metal stones 12 can be collected in turn.
